Akusti\u010dni neurom je poznat i kao vestibularni \u0161vanom je redak benigdni (nekancerogeni) tumor kojki raste na glavnom nervu koji se najstavlja na unutra\u0161nje uho sve do mozga. Grane glavnog nerva uti\u010du na balans i na slu, tako da pritisak na nerv usled akusti\u010dnog neuroma mo\u017ee izazvati nestalbilnost, gubitak ravnote\u017ee i gubitak sluha.<\/p>\n

Tumor mo\u017ee da raste sporo ili skoro uop\u0161te; me\u0111utim, u nekim slu\u010dajevima mo\u017ee se brzo razvijati izazivaju\u0107i jak pritisak koji mo\u017ee uticati na vitalne funkcije.<\/p>\n

 <\/p>\n

Simptomi<\/h2>\n

Simptomi kod akusti\u010dnog neuroma javljaju se kao posedica pritiska na glavni nerv i okolne nerve, krvne sudove i mo\u017edane strukture.<\/p>\n

Simptomi \u0107e se javiti kako se tumor razvija iako je mogu\u0107e da \u010dak i mali tumor izazove ozbiljne znake i simptome:<\/p>\n

Gubitak sluha (obi\u010dno se javlja postepeno ali u nekim slu\u010dajevima mo\u017ee biti iznenadan i ja\u010di na jednoj strani)<\/p>\n

Zvonjenje u o\u0161te\u0107enom uhu<\/p>\n

Gubitak ravnote\u017ee<\/p>\n

Vrtoglavica (vertigo)<\/p>\n

Utrnulost lica i slabost u retkim slu\u010dajevima<\/p>\n

U nekim retkim slu\u010dajevima akusti\u010dni neurom mo\u017ee smanjiti protok krvi i postati opasan po \u017eivot.<\/p>\n

Rana dijagnoza ovog stanja \u010de pomo\u0107i u spre\u010davanju rasta tumora i spre\u010davanja ozbiljnih posledica kao \u0161to su gubitak sluha i gomilanje te\u010dnosti u lobanji.<\/p>\n

 <\/p>\n

Uzroci<\/h2>\n

Akusti\u010dni neuromi se javljaju zbog gre\u0161ke u genu na hromozomu 22. Uloga ovog gena je da stvara protein koji kontroli\u0161e rast \u0160vanovih \u0107elija koje prekrivaju nerve. Razlog zbog gre\u0161ke u funkciji ovog gena jo\u0161 uvek nije utvr\u0111en; me\u0111utim, defektan gen se nasle\u0111uje kroz neurofibromatozu drugog tipa, koja je redak poreme\u0107aj koji izaziva rast tumora na nervima sa obe strane glave (bilateralni vestibularni \u0161vanomi).<\/p>\n

 <\/p>\n

Faktori rizika<\/h2>\n

Jedini faktor rizika koji je povezan sa akusti\u010dnim neuromom je roditelj sa neurofibromatozom tipa , koja je autosomalno genetsko stanje, \u0161to zna\u010di da se poreme\u0107aj mo\u017ee preneti sa roditelja koji nosi dominantni gen. \u0160anse su 50-50 da \u0107e dete naslediti ovu mutaciju od roditelja koji je ima.<\/p>\n

 <\/p>\n

Komplikacije<\/h2>\n

Akusti\u010dni neurom mo\u017ee izazvati nekoliko trajnih komplikacija:<\/p>\n

Gubitak sluha<\/p>\n

Nestabilnost ili gubitak ravnote\u017ee<\/p>\n

Zvonjenje u uhu<\/p>\n

Utrnulost lica\/oslabljenost<\/p>\n

Veliki akusti\u010dni neuromi mogu izazvati pritisak na krvotok prepre\u010davaju\u0107i normalni protok te\u010dnosti izme\u0111u mozga i ki\u010dmene mo\u017edine (cerebrospinalna te\u010dnost). Prekidanje normalnog protoka cerebrospinalne te\u010dnosti mo\u017ee izazvati nagomilavanje te\u010dnosti u glavi, poznato i kao hidrocefalija, koje mo\u017ee poja\u010dati pritisak u lobanji do nivoa kada postaje opasno.<\/p>\n","protected":false},"author":9,"featured_media":0,"template":"","yoast_head":"\nAkusti\u010dni neurom - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.humanitas.net\/sr\/diseases\/akustichni-neurom\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Akusti\u010dni neurom - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Akusti\u010dni neurom je poznat i kao vestibularni \u0161vanom je redak benigdni (nekancerogeni) tumor kojki raste na glavnom nervu koji se najstavlja na unutra\u0161nje uho sve do mozga.
